This is a example how to use the MVB Tags (custom fields) directly in your wordpress theme.

Look this site:
http://www.mmafightvids.com

The thumbail only appears in the index page, not in the video page! How!?

In MVB Settings:

MVB Post Template:

[videodescription]
[hide]
[videoplayer]

In the index.php of your theme: (Can be other name, depends of the theme)

Replace:

<?php the_content('Read...'); ?>

To:

<?php if(post_custom('mvb_thumb_url')) {?>
<a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><img src="<?php echo post_custom('mvb_thumb_url'); ?>" width="120" height="80" alt="<?php the_title(); ?>" border="0"></a>
<?}?>
<?php the_content(' '); ?>

In the code above, if the videopost has no thumbnail, notting happens, only the description will appears.

Also you can use this code to show a default image if the video has no thumbnail:

<?php if(post_custom('mvb_thumb_url')) {?>
<a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><img src="<?php echo post_custom('mvb_thumb_url'); ?>" width="120" height="80" alt="<?php the_title(); ?>" border="0"></a>
<?} else {?>
<a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><img src="URL_TO_DEFAULT_THUMB" width="120" height="80" alt="<?php the_title(); ?>" border="0"></a>
<?}?>
<?php the_content(' '); ?>

If you are changing the post template, try to use the “Post Rebuild” in the MVB Settings.

Have fun!!
